Two masked men armed with a gun, knives, axes and crossbows descended on a school in southern Brazil on Wednesday, killing five students and two adults before one killed the other and then himself, authorities said.

The men, identified as former students at the school in a suburb of Sao Paulo, also shot and killed the owner of a used car business nearby before launching the attack on the school, authorities said.

Ten people have been pronounced dead and 17 others are injured from this malicious attack.
